RESEARCH
My primary research interests center on the evolution and efficacy of amphibian antipredator mechanisms. These include: toxins, coloration, tail autotomy, morphology, and behavior. I am especially interested in individual differences as they affect survival. My students and I are looking at coevolution of tetrodotoxin bearing newts and their predators, using both field and laboratory trials to test hypotheses. We are also interested in the presence and function of tetrodotoxin in other groups of animals.
